     This Amendment No. 5 to Schedule 13D ("Amendment No. 5") amends the
Schedule 13D filed on September 19, 2005 (as amended by Amendment No. 1 thereto
filed on March 16, 2006, Amendment No. 2 thereto filed on March 17, 2006,
Amendment No. 3 thereto filed on July 25, 2006, Amendment No. 4 thereto filed on
June 14, 2007, and this Amendment No. 5, the "Schedule 13D") and is being filed
on behalf of Third Point LLC, a Delaware limited liability company (the
"Management Company") and Daniel S. Loeb, an individual ("Mr. Loeb", and
together with the Management Company, the "Reporting Persons"). This Amendment
No. 5 relates to the common stock, par value $0.625 per share (the "Common
Stock"), of Massey Energy Company, a Delaware corporation (the "Company"). The
Management Company is the investment manager or adviser to a variety of hedge
funds and managed accounts (such funds and accounts, the "Funds"). The Funds
directly own the Common Stock to which this Schedule 13D relates, and Mr. Loeb
and the Management Company may be deemed to have beneficial ownership over such
Common Stock by virtue of the authority granted to them by the Funds to vote and
to dispose of the securities held by the Funds, including the Common Stock.

Item 3.   Source and Amount of Funds or Other Consideration.

     Item 3 of the Schedule 13D is hereby amended and restated as follows:

     The Funds expended an aggregate of approximately $71,557,340 of their own
investment capital to acquire the 1,501,424 shares of Common Stock held by them.
The Funds effect purchases of securities primarily through margin accounts
maintained for them with Bear, Stearns Securities Corp. and Goldman, Sachs &
Co., which may extend margin credit to the Funds as and when required to open or
carry positions in the margin accounts, subject to applicable Federal margin
regulations, stock exchange rules and the firm's credit policies. In such
instances, the positions held in the margin accounts are pledged as collateral
security for the repayment of debit balances in the accounts.

Item 5.   Interest in Securities of the Issuer.

     Item 5 of the Schedule 13D is hereby amended and restated as follows:

     (a) As of the date of this Schedule 13D, the Management Company and Mr.
Loeb beneficially own 1,501,424 shares of Common Stock (the "Shares"). The
Shares represent 1.9% of the 81,099,178 shares of Common Stock outstanding as of
April 20, 2007, as reported in the Company's Quarterly Report on Form 10-Q for
the quarterly period ended March 31, 2007. The percentages used herein and in
the rest of this statement are calculated based upon this number of outstanding
shares.

     (b) The Management Company and Mr. Loeb share voting and dispositive power
over the 1,501,424 shares of Common Stock held directly by the Funds.

     (c) Schedule A hereto sets forth certain information with respect to
transactions by the Funds (at the direction of the Management Company and Mr.
Loeb) in Common Stock since the most recent filing on Schedule 13D. All of the
transactions set forth on Schedule A were effected in open market transactions
on the New York Stock Exchange. Other than as set forth on Schedule A, since the
most recent filing on Schedule 13D there were no transactions in the Common
Stock

                                       4


effected by the Reporting Persons nor, to the best of their knowledge, any of
their directors, executive officers, general partners or members.

     (d) Other than the Funds which directly hold the Shares, and except as set
forth in this Item 5, no person is known to have the right to receive or the
power to direct the receipt of dividends from, or the proceeds from the sale of,
the Shares.

     (e) Each of the Reporting Persons ceased to be the beneficial owner of more
than five percent of the outstanding Common Stock on August 1, 2007.
